sessions in juno

[axh...@gmail.com]

Hi,

I am testing the session in juno. I tried the example below but am not
able to get it working. Is there something I am missing?

Ashish
------------------
Code used:
from juno import *

init({'dev_port':8080, 'use_templates':False})
@get('/foo/')
def foo(web):
web.session['msg'] = 'hello there'
web.session.save()
redirect('/bar/')

@get('/bar/')
def bar(web):
return web.session['msg']

run()

----------------

Stack trace:

Sessions are disabled by default, so you'll need to add
"'use_sessions': True" to the init() parameters.

You'll need to add {'use_sessions': True} to your init() call (they're
disabled by default, and web.sessions is set to None if they're not
enabled). You'll need Beaker (http://wiki.pylonshq.com/display/beaker/
Home) to use them.

Hmm... are you going to /bar/ before you go to /foo/? That's the only
way I've managed to get that error with your code.

[axh...@gmail.com]

No, I am doing /foo/, I get redirect to /bar/ and I get the error.

I am on

And using Beaker-1.2.3


Is there anything I can test or do to debug this issue?

Hi Brian,

Sorry, it was all my mistake. I selectively allow cookies in my
browser and had forgotten to allow cookies for the domain. Things work
fine now.
